YPBIND(8)               OpenBSD System Manager's Manual              YPBIND(8)

     ypbind - create and maintain a binding to a YP server

     ypbind [-ypset] [-ypsetme] [-insecure]

     ypbind finds the server for a particular YP domain and stores information
     about it in a binding file. This binding information includes the IP ad-
     dress of the server associated with that particular domain and which port
     the server is using.  This information is stored in the directory
     /var/yp/binding in a file named with the convention DOMAINNAME.version.
     (The YP system only supplies information on version 2.)

     When ypbind starts the primary domain (or gets the first request for a
     new domain), it checks if a file for the domain in question exists in the
     directory /etc/yp/ (ie. /etc/yp/DOMAINNAME).  If such a file exists, it
     will list the hosts which ypbind should restrict it's server search to.
     Otherwise, ypbind assumes it will need to use broadcasts to find a valid
     server.  Using either of these techniques, ypbind will search for a serv-
     er willing to serve maps for the client's domain.  Once a binding is es-
     tablished, ypbind maintains this binding by periodically communicating
     with the server to which it is bound.  If the binding is somehow lost,
     e.g by server reboot, ypbind marks the domain as unbound and attempts to
     re-establish the binding.  When the binding is once again successful, yp-
     bind marks the domain as bound and resumes its periodic check.

     The options are as follows:

     -ypset    ypset(8) may be used to change the server to which a domain is

     -ypsetme  ypset(8) may be used only from this machine to change the serv-
               er to which a domain is bound.

               permit binding to a ypserv(8) on a non-reserved port.  This is
               needed if receiving maps from SunOS 3.x or Ultrix.

     The -ypset and -ypsetme options are dangerous and should be avoided.  For
     greatest security, the use of a server list in /etc/yp/DOMAINNAME is rec-
     ommended.  The file should contain a list of valid YP server hostnames,
     with one hostname per line.  The comment character is #.

     If the directory /var/yp/binding exists, YP is started automatically at
     boot time by /etc/rc.

     /var/yp/binding/DOMAINNAME.version - binding file for domainname
     /etc/yp/DOMAINNNAME - server list for this particular domain

     domainname(1),  ypcat(1),  ypmatch(1),  yppoll(8),  ypset(8),
     ypwhich(1),  ypserv(8),  yp(8)

     Once ypbind is running you should look at the following pages to see how
     to enable YP support for each of the following maps: passwd(5),
     group(5),  hosts(5),  resolv.conf(5),  ethers(3),  networks(5)
